摘要
介绍CBTC系统的车-地无线通信方式和工程应用情况。在北京地铁运营线路隧道里进行了漏泄同轴电缆的CBTC系统车-地无线传输专项试验,测试了2.4 GHz漏泄同轴电缆在地铁隧道工作环境的路径损耗,并与生产厂提供的理论值进行了对比分析,为以后漏泄同轴电缆在CBTC系统车-地无线通信的工程实施提供链路设计依据。
In Beijing metro operational tunnels, special testing on leaky coaxial cable is conducted on train - trackside wireless transmission in CBTC system. The path loss is tested on the 2.4 GHz leaky coaxial cable in tunnel, and a comparative analysis on theoretical value provided by the manufacturer is conducted, providing a design basis for train- trackside wireless communications of leaky coaxial cable in CBTC system.
